About

Merfolk guardians are the chosen of nature and its divine protectors. They are more mystical than other merfolk, and also more savage, mysterious, and close to nature. Sometimes, they live among other merfolk as special protectors, but there are entire tribes of merfolk guardians as well. Tribes of these merfolk seem forbidding even to other merfolk.
